Answer:
48 centimetres wide
Step-by-step explanation:
you are at 3
you enlarge it and you get 6
second enlargement you get 12
third enlargement you get 24
fourth enlargement you get 48
if you times 3 by 4 you are not doubling the width each time you enlarge the photo
so it is easier to double it each time you enlarge it
<span>To determine the number of lawns he needs to mow to earn the desired money, Eli could perform a simple addition problem, adding $21 per lawn until he reached his goal number. This equation would be: 21 + 21 = 42 + 21 = 63 + 21 = 84 + 21 = 105 + 21 = 126 + 21 = 147 + 21 = 168 + 21 = 189 + 21 = 210 + 21 = 231 + 21 = 252. However, a better way would be to divide the desired amount by the cost per lawn and round to the nearest whole number. That equation is 235 / 21 = 12 lawns.</span>
Answer: 
Step-by-step explanation:
It is important to remember that the formula for calculate the area of a square is:
Where "s" is the side lenght of the square.
From the figure you can identify that the side lenght of the square can be represented with this expression:
Therefore, the following expression represents the area of the square:
In order to simplify it, you need to remember that:
Then, you get that the polynomial that represents the area of the given square, is:
